External roller shutters are available in two systems; adaptive and superstructure. The adaptive system is dedicated to existing buildings, and the extension system to buildings under construction – it is flush-mounted. Both systems are available in a wide range of colors, thanks to which they can be easily adapted to the facade or window joinery. What distinguishes these systems is thermal insulation. Thanks to this the heating costs of the building are reduced. In addition, external roller shutters can be controlled manually or with a remote control, which is very convenient.
